In the ASLAC device, a coefficient, h
as C
x is the position of this CSD coefficient within the h
The next most significant binary 1 is represented by x = 2, and so on.
Thus, C

The number of CSD coefficients, N, is limited to 4 in the GR, GX, R, X, Z, and the IIR part of the B filter, and 3 for
the FIR part of the B filter. Note also that the GX-filter coefficient equation is slightly different from the other filters.
Please refer to the Am79213/Am79C203/031 Technical Reference, PID 21325A detailing the commands for
complete details on programming the coefficients.
